Orientation Determination in Telecommunication Systems

Abstract

The present subject matter relates to an apparatus for a wireless communication system. The apparatus comprises means being configured for: receiving from antennas of another apparatus, herein referred to as user apparatus, antenna signals respectively; determining ranges between the apparatus and the antennas of the user apparatus using the multiple antenna signals; determining an orientation of the user apparatus using the determined ranges.

1 . An apparatus for a wireless communication system, the apparatus comprising:
 one or more processing portions, and   memory storing instructions that, when executed by the one or more   processing portions, cause the apparatus to perform:   receiving from antennas of another apparatus, herein referred to as user apparatus, antenna signals respectively;   determining ranges between the apparatus and the antennas of the user apparatus using the antenna signals;   determining an orientation of the user apparatus using the determined ranges.   
     
     
         2 . The apparatus of  claim 1 , the apparatus configured for determining the ranges using at least one of the following: carrier-phase measurements or code-phase measurements. 
     
     
         3 . The apparatus of  claim 1 , the apparatus configured for repeatedly performing the receiving of antenna signals, the determining of the ranges and the determining of the orientation. 
     
     
         4 . The apparatus of  claim 1 , the apparatus configured for determining the ranges using a configuration of the user apparatus, the configuration indicating at least one of the following: a body frame of the user apparatus or positions of the antennas with respect to a center point of rotation of the user apparatus. 
     
     
         5 . The apparatus of  claim 4 , the apparatus configured for receiving the configuration from the user apparatus. 
     
     
         6 . The apparatus of  claim 1 , the apparatus configured for receiving the antenna signals simultaneously, concurrently or quasi concurrently. 
     
     
         7 . The apparatus of  claim 1 , the apparatus configured for determining a location of the user apparatus using the determined ranges. 
     
     
         8 . The apparatus of  claim 1 , the apparatus configured for sending the determined orientation to the user apparatus or to another apparatus that provides based on the orientation content to the user apparatus. 
     
     
         9 . The apparatus of  claim 1 , the orientation a relative orientation or absolute orientation. 
     
     
         10 . The apparatus of  claim 1 , the apparatus configured to receive the antenna signals through a radio interface or a direct link interface. 
     
     
         11 . The apparatus of  claim 1 , the apparatus configured for sending the determined ranges to the user apparatus. 
     
     
         12 . A user apparatus for a wireless communication system, the user apparatus comprising:
 one or more processing portions, and   memory storing instructions that, when executed by the one or more processing portions, cause the user apparatus to perform:   receiving a signal from another apparatus at multiple antennas of the user apparatus, resulting in multiple antenna signals;   determining ranges between the other apparatus and the antennas of the user apparatus using the antenna signals;   determining an orientation of the user apparatus using the determined ranges.   
     
     
         13 . The user apparatus of  claim 12 , the received signal being a Positioning Reference Signal. 
     
     
         14 . A user apparatus for a wireless communication system, the user apparatus comprising:
 one or more processing portions, and   memory storing instructions that, when executed by the one or more processing portions, cause the user apparatus to perform:   receiving a signal from another apparatus at multiple antennas of the user apparatus, resulting in multiple antenna signals;   determining ranges between the other apparatus and the antennas of the user apparatus using the antenna signals;   sending the determined ranges to the other apparatus for determining by the other apparatus an orientation of the user apparatus using the sent ranges.   
     
     
         15 . The user apparatus of  claim 14 , the received signal being a Positioning Reference Signal. 
     
     
         16 . The user apparatus of  claim 14 , the user apparatus configured for receiving the orientation of the user apparatus from the other apparatus.
